There’s no denying that the Underdog promo code TOPACTON is the best NBA DFS promo for Tuesday, March 3. Need more proof? DFS expert Daniel Preciado says it best:
“There’s no reason to wait—Underdog’s promo code TOPACTION is your fastest path to $75 in fantasy bonus entries. Every savvy DFS player should be claiming this now before Tuesday’s games start. Missing it is leaving easy money on the table.”
Here’s how it works: Underdog lets you submit a lineup using player projections from any NBA game. Simply select “Higher” or “Lower” on a projection to add that pick to your lineup. The more picks you add, the bigger your potential payout—an 8-for-8 perfect lineup pays out up to 120x.
If your lineup has three or more picks, you choose between a Standard or Flex entry:
- Standard lineup: Earn the largest payout, but only if every pick wins.
- Flex entry: Earn a smaller payout on a perfect lineup, but still profit (or get your entry back) with one losing pick.

| Player | Team | Pick |
| Tyrese Maxey | Philadelphia 76ers | Higher Than 40.5 Points + Assists + Rebounds |
| Stephon Castle | San Antonio Spurs | Lower Than 4.5 Rebounds |
| Jalen Green | Phoenix Suns | Lower Than 18.5 Points |
Tyrese Maxey has been lighting it up lately, entering this matchup with four straight games of 42 or more combined points, assists, and rebounds. With Joel Embiid still out for the 76ers, Maxey should put up another big stat line against the Spurs.
On the other side, Spurs guard Stephon Castle has averaged nearly five rebounds per game this season, but his recent numbers have dipped. Castle has failed to hit five rebounds in four straight games and has only reached that mark once in his last eight contests. Expect another quiet rebounding performance against Philadelphia.
Jalen Green has only played in 12 games this season and hasn’t been much of a scoring threat. He’s surpassed 19 points just twice this year, including only once in his last 11 games. Don’t expect a big performance from the Suns guard tonight.
